CEMENT-APPLYING MECHANISM.

Specification of Letters Patent.

Application filed February 8, 1907.

Patented July 4, 1911.

Serial No. 356,308.

To all whom it may concern:

Be it known that I, EZRA E. C. PACKARD, a citizen of the United States,residing in Lynn, county of Essex, and State of Massachusetts, haveinvented an Improvement in Cement-Applying Mechanism, of which thefollowing description, in connection with the accompanying drawing, is aspecification, like letters on the drawing representing like parts.

This invention has for its object to provide a novel cement applyingmachine for delivering cement on the surface of stock on a stocksupport, or being fed through the machine.

In accordance with my invention, I have combined with suitable mechanismherein shown as of the class employed in ordinary skiving machines, areceptacle to receive cement, and a cement delivery nozzle provided witha valve that is moved within the nozzle by contact of the exposed end ofthevalve with the stock sustained by any usual stock feeding wheel orsupport, said valve having a connected spring that acts when the stockis absent from the feeding wheel to maintain the valve closed.

Figure 1 in front elevation shows part of a machine with which I haveembodied my invention in one of the best forms now known to me; Fig. 2is an enlarged sectional detail of the nozzle and its valve closed; andFig. 3 a detail showing the upper end of the receptacle.

The framework A, the shaft A on which is mounted the stock-feeding wheelB, the disk presser B for acting on the upper side of the stocksustained on the feeding wheel, its carrying shaft 13 and wheel B drivenby belt D driven from any usual pulley at the opposite end of shaft A,are and may be all as usual.

I have mounted on the end of the overhanging arm A" of the framework, areceptacle G for cement or other liquid adhesive, said receptacle havingat its lower end a foot C having a hollow shank extended through saidarm, said foot being provided with a passage for the reception of a cockC having ahandle C and a transverse opening, a port a leading from saidreceptacle to said opening, a second port a leading through said shankinto a suitable flexible tube a cement passing from said receptaclethrough said cock when opened into a nozzle D secured to a dependingportion A of the framework in suitable mannor as by screws D. The nozzleD is rigidly secured in place and its end therefore occupies a fixeddistance from the feeding wheel or stock-support.

The upper end of the receptacle C has fitted closely therein a hollowplunger 1) that rests on the top of the cement in said receptacle, theplunger having an inturned hub 6*, see Fig. 8, on which acts the lowerend of a screw 6 having a handle 11 by which the screw may be turned toforce the plunger into the receptacle to force the cement therefromthrough the open cock G into the nozzle. The receptacle has two rods 6that serve as guides for the cross head at that sustains the screw Z).The cross head has at its ends screw rods cl made adjustable verticallyby thumb nuts 0Z said rods having connected to their lower ends theupper ends of springs 0Z attached at their lower ends to studs d Thevalve D has a stud 2 that is extended outwardly, see Fig. 2, through aslot 3 in the nozzle where said stud has connected with it a spring 6attached at its opposite end to a stud e fixed to part of the nozzle,said spring acting normally to move said valve in the direction of thearrow thereon, Fig. 2, so that its inclined face 4 is held firmly on theinclined seat 5, the lower end or toe 6 of the valve extending beyondthe lower end of the nozzle, the extremity of said toe when the valve isclosed being arrested a short distance from the upper side of thefeeding wheel.

When stock to be cemented is laid on the feeding wheel the upper side ofthe stock by contact with the toe 6 of said valve D raises the sameslightly in the nozzle against the stress of the spring 6, thus forminga space between the face 4|: and seat 5 through which cement may issueonto the stock.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is In a machine of the character described thecombination of stock supporting and feeding means, a receptacle forcement, a nozzle connected to said receptacle and having its mouth at afixed distance from and close to said stock-supporting means andprovided with an inclined valve seat at its mouth, a valve for saidnozzle having an inventing the escape of any cement when no stock isbeneath the nozzle month.

In testimony whereof, I have signed my name to th1s speclficatlon, 1nthe presence of two subscrlblng witnesses.
